Referring more in detail to the drawings:

1 designatesa vehicle, such as a tractor or the like, having a plurality of wheels 2, axles 3 and 4 for supporting outer ends of longitudinal frame members 5 and 5', as shown to be cicrular formation and may be of a tube, if desired, upon which is mounted a platform 6 by brackets 7 and S rigidly secured to the member 5 by welding or The vehicle is hydraulically driven,

mounted on the platform for the operator o'f the vehicle.

A platform 16 is mounted on the rear portion of the vehicle by brackets or the like 17 and mounted thereon 1s an engine 18 with a housing 18 and pumps 19, 20 and 21 for operating the hydraulic motors of the vehicle, as later described. 21 designates a cover for the pumps.

The inner ends of the longitudinal frame members 5 and 5 are spaced apart and rigidly mounted between the ends of the tubular members 5 and 5 is a substantially' rectangular shaped frame forming substantially U-shaped` members 22 and 23 extending laterally of the frame members 5 and 5', illustrated to be of tubular formation and mounted between the platforms 6 and 16. The U-shaped frame members and longitudinal frame may be tubular` and utilized as a reservoir for fluid supply, if desired. Mounted on the members 22 and 23 and extending y transversely of the vehicle are channel trackways 24 and i 25 and on the upper faces thereof are mounted gear racks 26 and 27. t

28 designates a ram or shaft for a hammer head` 29 `for breaking the pavement or the like and in order to movably mount the hammer on the vehicle, I provide a carriage frame 30 having side brackets 31 and 32 and ends 33 and 34. Movably mounted inside the upper parts of the side brackets 31 and 32 by pins 35 or the like, as n-V dicated at 35', is a hammer swivel framev 36 consisting of U-shaped side members 37 and ends 38 for a purpose later to be described. Mounted on'the respective side brackets 31 and-32` near the ends 33 and 34 are Yrol-1ers or wheels 39 and 40 adapted to engage in the trackways 24 and 2,5 for movement off ther carriage on said. trackways. The wheels are mounted on the shafts r4^1and 421ca`rried in the respective-corners of the yside lbracket arms 31 and 32. Movably mounted upon the respective ends 38 of the swivel frame 36 by 'pins 43A or the like are U-shaped members 44 and 44 of a hammer Yframe 43'. The U- shaped members are-spaced from the ends 38 by blocks 45. The hammer vframe 43has rigidly mounted on the arms ofthe U-shaped members 44 yand 44', spaced elongated, verticallyextending angle members or guides 46 and 47 defining ways therebetween. Slidably arranged inside the angle members-46 and 4'7 respectively are plates 48 and 49 of a ram frame 50, said side plates having side ,edgestengaged in said ways and having their lower ends connected by side braces 50'. Rigidly mounted on the upper ends of thefplates 48-and 49 on the respective sides thereof are angle-shaped members 52 and 53 upon which is mounted a head plate 54 which connects said angle shaped members 52 and 53 and supports a motor 5S having a shaft 56 extending from each side thereof for mounting pulleys 57 and 58 having V-shaped grooves.

Secured to the upper edge of the respective plates 48 and 49 are bearings 59 for shafts 60 and 60 upon whichare mounted spaced pulleys or crank plates 61 and 62. The pulleys also have a plurality of grooves, as indicated at 63, and adapted to run over the pulleys 57 and 58 and 61 and .62 are V-belts 64 and 65 rotating the pulleys 61 and 62 from the operation of the motor 5S. A pair of channel guide members66 and 67 are secured to the inside of the plates 4 8 and 49 near the lower end of said members and in which the ram 28 is adapted to engage and be reciprocated. The ram is provided near its upper end and on each side thereof, with outwardly extending ears 69 and 70. Helve links 71 and 72 are provided having one end pivotally attached to the ears 69 and 70 by pins or the like 73 and their other end pivotally attached by bolts or the like 74 to arms 75 and 76. The upper ends of said arms are pivotally secured to arms 77 and 78, the center. of which is sleeved over a pin 79 extending through and carried by one side edge of the pulleys or crank plates 61 and 62, the arms 75 and 76 being secured to the arms on the pin 79 by pins or the like 80; The arms work in the space between the pulleys 61 and 62. A helve spring 81 has its respective ends engaging in keepers 82 on the respective inner sides of the arms 75 and 76, as best illustrated in Fig. 2. The arms 77 and 78 have a sleeve bearing, as indicated at 83 (Fig. 2) so that the arms are loosely mounted on the pin 79. The tamper foot or head 29 is mounted on the lower end of the ram by tapered pins, as indicated at 85. e

The end plate 33 of the carriage frame 30 has an outwardly extending arm 86 adapted to receive the end of a piston rod 88 of a cylinder 89 having its upper end pivotally attached to outwardly extending ears 90 secured to a bracket 91 on theV outside of the vertical angle members 46 and 47. The piston and the cylinder 89y are operated by fluid from pump 19 for swinging movement ofthe swivel frame together with the hammer frame transversely of the vehicle when it is desired to use the hammer when 'the frame of the vehicle is setting at an angle. By

straightening ofthe hammer frame to the vertical through operation of the hydraulic cylinder, this may be` accomplished. The swivel frame is pivoted on pins or bolts ,35y secured in the trop of the side brackets 31 and and tlirouglgi` the side arms 37 of they swivel frame` 36.

The hammer frame 43' which consists of U-shaped members 4.4 and 44', and angle members or guides 46 and 47, may also be rotated or moved longitudinally of the vehicle or. slanted longitudinally of the vehicle on pins 43 extending through the ends 38 of the swivel frame 36 and the U-shaped members 44 and 44 whichare rigidly secured to the angle members 46 and 47, the pins 43 forming a bearing for rotation of the hammer frame. This movement of the hammer frame together with the ram frame 50, fore and aft is accomplished by a cylinder 99 having its end pivotally secured to ears 100 extending outwardly from a bracket 101 having its ends secured tothe side of said vertically extending angle members 46 and 47, as best illustrated in Fig. 2. The cylinder has a piston rod 102 having its lower end pivotally secured to ears 103 mounted on one of the side members 37 of the swivel frame 36, as best illustrated in Fig. 2. Fluid from pump 19 will operate the piston in the cylinder to move the hammer frame fore and aft of the vehicle.

The ram frame 50 which consists of the plates 48 and 49, side braces 50', angle members 5,2 and 5,3, Ahtldpllte 54, guide members 66 and 67 and plates 107 andv108 which connect the upper ends of the angle guide members 52 and 53. The ram frame may be raised and lowered Atogether with ram 28 with respect to the carriage by means of hydraulic cylinders 1 05 and 106 having their upper ends secured to outwardly extending ears 107 and y108 on the plates 107 and 108, as best illustrated in Fig. 3L

The cylinders and 106 are provided with pistons having rods extending downwardly and pivotally secured to outwardly extending ears 109 and 110 secured to the lower ends of the plates 48 and 49. By operating the cylinders 105 and 106, they will cause the plates which carry the pulleys 61 and 62 and the angle-shaped members SZand 53 carrying the plate 54 and motor 55 to be raised and lowered within the vertically extending angle members .or guides 46 and 47 to regulate the distance of the hammer from the object to be contacted, either the pavement oi'V earth material which it is adapted to strike.

The axles 3 and 4 of the vehicle are housed within housings 111 and 112 connected by plates 113 and 114, the centers of which are provided with planel surfaces, as indicated at 115, and are Vprovided with openings adapted to receive pins 116 extending through aligned openings in ear-like members 117 whichr are extended from walls 117 on housings 118 and 118 turnably secured to the longitudinal frame member 5, as now to be described. Rigidly secured to the ends of the housing 118' by welding or other suitable means is a collar 119 having an upwardly extending arm 120 with pivoted ears 121 adapted to receive the end of a hydraulic cylinder 122 having piston rod 123 with their ends attached to ears 124 of an arm 125 welded or otherwise suitably secured to a collar or ring 126 on the longitudinal frame member 5', as best illustrated in Fig. 10. The cylinder 122 is connected ,tol the pump 19 as later described, whereby said cylinder 122 may be operated to extend or retract the piston rod 123. Extension or retraction of piston rod 123 moves arm 125 which rotates the longitudinal frame Vmember 5 and thereby members 22, 23 and 5 about the longitudinal axis through the longitudinal members 5 and 5. Said rotation is relative to axles 3 and 4 due to arm 120 being fixed to collar 119 on housing 118. The forward end of the longitudinal member 5 is provided with an enlarged ring or collared end 127 which engages against a collar 128 of the housing 118 similar to the ring or collar on housing 118. The ears 121 and 1214 have pins 121 and 124 extending outwardly therefrom adapted to engage in openings 127 in the ends of a plate 128 for locking the main frame in position. u

The ends of the longitudinal members 5 andS' are provided with closure plates 130 which are of a slightly larger diameter than the frame members and yare rigidlyl secured to the frame members by means of bolts'131 or the like. The ends 129 extend into the housings 118 and 118" and through the collars 119 and 128, The ends also extend through an opening 132 in the walls 1 17 and are kept in place by the closure plates 130, in other words, the housings 118 and 118 are retained between the collars 126 and 127 of the ends 129 and the closure plates 130 respectively.

The hydraulic cylinders 12 and 13, provided for Steerage of the vehicle, are mounted between the housings 118 and 111 and housings 118 and 112. The upper part of the cylinders -is pivotally mounted on extending ears 133 on the housing 111 and 112 and the piston rods having connection to ears 134 on the housings 118 and 118'. In Fig. l0, I have only shown the mounting of the steering cylinder 12 but the connection of the cylinder 13 to the front axle and the longitudinal frame 5 would be similar.

The plate 135 is secured on the end 34 of the hammer carriage 30 and mounted thereon is a motor 136 having shafts 137 and 138 extending to the gear rack 26 and 27 and mounted on the shafts are gears 139 and 140 adapted to engage the teeth 141 on said gear racks for movement of the carriage longitudinally of said racks and laterally of the frame.

The hydraulic iluid system for operating the vehicle and the hammer mechanism, as well as the drilling arrangement, as partly above described, is diagrammatically illustrated in Fig. ll wherein the operating arrangement for the valves may be mounted on the platform 6 near the drivers seat 15, as indicated at 142.

Referring specically to Fig. 11, 143 designates a valve for operating the vehicle driving motors and 11 and are connected by lines 144 and 145 to branch lines 146 and 147. Line 148 leads from the valve 143 to the pump 20 having connection with a line 149 which leads to the fluid supply tank 9.

A valve 150 connects with motor 55 through lines 151 and 152. The valve also connects with a two-way valve 153 through line 154. Valve 153 has connection with line 148 through line 155 and also connects with the pump 21 through line 156 which also connects with line 149 leading to the supply tank 9. The operation of the motor 55 will cause the belts 64 and 65 operating over pulleys or crank plates 61 and 62 to rotate said crank plates thereby causing the ram 28 with the hammer or tamper foot thereon to be raised through the helve arms 75 and 76 and links 71 and 72, respectively. By regulating the speed of the motor 55, the speed of the hammer may be regulated to suit the user. It will be noted valves 143 and 150 have return lines 143 and 150 connecting with Vline 161 for return of fluid to the tank 9.

A valve 157 connects with motor 136 through lines 158 and 159 to move the carriage on the gear racks 26 and 27. Valve 157 has a line 160 leading to the pump 19 which in turn is connected to the reservoir tank 9 through line 149. Valve 157 also has a return line 161 leading back to the tank.

The cylinder 89 is connected to a valve 162 through lines 163 and 164. The valve 162 also connects with line 160 which leads to pump 19. The valve is also connected with line 161 through line 165. Cylinder 99 is connected to a valve 166 through lines 167 and 168 which valve also connects with the line 170 through branch lline 169 to line 160 leading to pump 19 and also connects with the return line 161 through line 171. The cylinder 89 is for tilting the hammer frame transversely while the cylinder 99 is for tilting the hammer frame longitudinally of the vehicle.

The cylinders 105 and 106 are connected to the valve 172 through lines 173 and 174 and the valve is also connected to line 160 leading to pump 19 through line 175 and to the return line 161 by branch line 176. The cylinders are the vertical cylinders that raise and lower the hammer frame.

The cylinder 12 has lines 177 and 178 connected to a valve 179 which has a branch line 180 leading to line 160 which is connected with the pump 19. A line 181 is connected to the return line 161 leading to the supply tank 9 by a valve 182 for the steering cylinder 13. The cylinder 13 nas unes 1:53 and 184 leading to the valve 182 having connection with line 161 and line `181 to the valve 179 and through line 180 to yline 160 leading to pump 19. The valves are operatedfor steering the front and rear wheels independently of each other.

The cylinder 122 (not shown in Fig. 11) will also have similar lines leading to a valve mounted on the platform 6 and connections to the pump 19 and supply tank 9 for operation of the cylinder for controlling the tilting of the frame with respect to the vehicle.

An extension rack 200 may be provided for connection to one side of the gear racks 26 and 27 by extension of U-shaped frame 201 having channel-shaped side arms 202 so that the wheels or rollers 39 and 40 may travel therein.

` The extension is connected to the main gear rack by a hinge member 203 which comprises arms 204 and 205 connected at their ends by pin 206, as best illustrated in Fig. 9, that the extension may be extended horizontally or it may be elevated upwardly or lowered downwardly from the plane of the main gear rack, as desired. In order to lend support to the extension, I attach to the carriage frame standards 207 and 208 having brace arms 209 and 210 provided with top plate 211 to which are attached chains or the like 212 having their outer ends secured to plates 213 mounted on the end 214 of the extension.

Fig. 8 has illustrated a hinge member having the arms in vertical position and Vwhich if it is desired to have the extension elevated upwardly, the upper arm is used for the pin member, and indicated at 215, and the lower opening used when the extension is desired to be used at a lower elevation than the main rack.

This form of hinge, as illustrated in Fig. 5, wherein an elongated rack member 216 is used having the same channel members for the wheels on the carriage member and gear rack as in the main gear rackmechanism. On the outer end of the extension 216 is a frame 217 having spaced axles 218 and 219 for mounting wheels 220 and 221. The frame includes a mounting 222 for a motor 223 having a `chain and sprocket connection 224 with the axle 218, as illustrated in Figs. 5 and 7, for driving of the outer end of the extension along with the vehicle when the vehicle is being moved so as to prevent side draft on the extension.

In operation of the apparatusl assembled and constructed as described, the vehicle may be moved by operation through the motors 10 and 11 by operation of pump 20. The operation of the two-way valve 153, which has connection with pump 21, may be utilized for moving the vehicle. Also, the operation of the two-way valve 153, which has connections through lines and 148 with pump 20, this pump may also be utilized for operating the hammer through motor 55.

It will be obvious from the foregoing that I have provided an improved apparatus on the hydraulic driven vehicle with a uid medium supply on the vehicle for movement of the vehicle; hydraulic means for movement of the carriage frame on the vehicle frame in transverse and fore and aft position with respect to the vehicle, as well as for movement of the hammer frame in the main vertical frame for raising and lowering the tamping head with respect to the work. By utilizing the hydraulic means for moving the tamping ram and head in various positions and for movement of the carriage laterally of the vehicle, I have provided an extremely mobile device and further the extensions on the lateral portions of the frame enable use of the hammer at a distance to the side of the vehicle, either in a raised or lowered position.
